ABSTRACT
El desplazamiento forzado afecta a más de 5 millones de personas en Colombia. El proceso de movilidad que experimentan los desplazados implica el debilitamiento de los vínculos con su entorno relacional y supone la privación del derecho de incidir a nivel sociopolítico. El sentido de comunidad, la participación y el empoderamiento sirven para comprender tanto el proceso de adaptación en la comunidad de destino, como el incremento de la participación comunitaria. Desde un enfoque estructural, el Análisis de Redes Sociales hace posible evaluar las redes de apoyo social de la población desplazada. Los objetivos de la investigación son (a) evaluar los tres procesos mencionados, (b) analizar las redes personales de los participantes y (c) examinar los posibles efectos que la estructura de las redes personales pueda ejercer sobre el desarrollo de los procesos comunitarios analizados. Los resultados indican que las propiedades estructurales de las redes inciden en el nivel de participación en actividades de desarrollo comunitario. Sin embargo, no se han detectado relaciones significativas entre los indicadores estructurales y los otros dos procesos comunitarios evaluados. Existen evidencias que indican que la densidad contribuye positivamente sobre la participación mientras que los parámetros de centralización afectan de forma negativa. Concluimos discutiendo el alcance de nuestros resultados para diseñar estrategias de intervención que promuevan la integración plena de los desplazados en la comunidad receptora.
Forced displacement affects over 5 million people in Colombia. The process of mobility experienced by displaced implies the weakening of the linkages with their relational environment and may involve the deprivation of the right to decide at socio-political level. The sense of community, the community engagement and the psychological empowerment display a strong potential to understand both the adaptation process in destination community, and the increase in community involvement. From a structural viewpoint, Social Network Analysis allows to evaluate the social support networks of the displaced population. The aims of this study are: (a) assess the three community processes; (b) analyze the personal networks structure of the displaced population; and (c) identify the potential effects that personal networks may exert on the development of community processes. Results suggest that structural properties of networks impact on the level of participation in community development activities. However, no significant relationships were identified between the structural measures and the other two community processes evaluated. Density contributes positively on community participation while centralization parameters affect in a negative way. We conclude discussing the applications of our results to design effective intervention strategies to promote the full integration of displaced population in the host community.

El siguiente artículo recoge la propuesta metodológica de una investigación que se formuló con el propósito de dar cuenta de las razones que explican la diferente presencia que, a nivel territorial, expresan las Farc al término del periodo 1998-2010, tiempo en que la estrategia contrainsurgente del estado colombiano si bien logró desplazar a esta guerrilla de algunas regiones del país, en otras no lo consiguió. La perspectiva metodológica aquí planteada propone una estrategia analítica para identificar, definir y comprender las causas de la diversidad regional de la geografía de la guerra en Colombia. Tal estrategia se enfocó desde una óptica comparada a partir de un modelo desarrollado por la ciencia política denominado Conjunto de Variables para el Análisis Comparativo Cualitativo (csQCA en sus siglas en inglés, crips set of Qualitative Comprative Analysis).
The following article contains the methodological proposal of a piece of research that was carried out in order to give an account of the reasons which explain the different presence that, at the territorial level, the FARC express, at the end of the 1998 2010 period. That was a time in which the counterinsurgency strategy of the Colombian State even though it managed to move the guerrillas in some regions of the country, in others did not. The methodological perspective, which is posed here, proposes an analytical strategy to identify, to define, and to understand the causes of the regional diversity of the geography of the war in Colombia. Such a strategy has shifted from a comparative perspective based on a model developed by the political science called Set of Variables for Qualitative Comparative Analysis (csQCA in its acronym in English, crips set of Qualitative Comparative Analysis).

PURPOSE: The purpose of this study was to evaluate the injury mechanism of pelvic bone fracture and injury type and treatment of bladder rupture associated with pelvic bone fracture. MATERIALS AND METHODS: From September 2002 to February 2011, we treated pelvic bone fracture with bladder rupture in 56 cases with minimal follow up of one year. Each of the 56 cases was classified into groups depending on the mechanism of pelvic fracture (Young classification) and the aspect of bladder rupture (intraperitoneal rupture, extraperitoneal rupture, combined rupture) after which the relationship between the two aspects was analyzed retrospectively. RESULTS: There were a total of 56 cases where bladder ruptures occurred in association with pelvic bone fractures; 34 patients were men and 22 patients were women. The average age was 58.2 years (range: 19-84). Traffic accidents were the main cause of pelvic bone fractures with bladder ruptures in 41 cases. The main injury mechanism was lateral compression, and pubic ramus fractures occurred in 38 cases (67.9%). Regarding the classifications of bladder ruptures, there were 17 cases of intraperitoneal rupture, 37 cases of extraperitoneal rupture, and two cases of combined rupture. Operations were performed on all cases of intraperitoneal and combined rupture and on six cases of extraperitoneal rupture. CONCLUSION: Lateral compression was the most common injury of bladder rupture in pelvic bone fracture. Bladder ruptures occurred even in cases where the displacement of pelvic bones was not severe and also in cases of low energy injury.

Fractures of the femoral neck in elderly patients can be treated by internal fixation, hemiarthroplasty, or total hip arthroplasty (THA), and the treatment modality used should be determined on the basis of considerations of the degree of fracture displacement, age, functional demands, and the risk factors for surgery and anesthesia. We studied 85 active elderly patients who underwent minimally invasive two-incision THA or conventional bipolar hemiarthroplasty (BHA) within 2 weeks of injury for the treatment of acute displaced femoral neck fractures. Patients were followed up for a minimum of 24 months. The average operation times were 70 minutes in the THA group and 46 minutes in the BHA group (p=0.002), and average blood losses during the perioperative period were 921 cc and 892 cc, respectively (p=0.562). In the THA group, the average postoperative Harris hip score was 88.3 and the average Western Ontario and McMaster University score was 28.8, whereas in the BHA group the corresponding scores were 80.4 (p=0.006) and 32.5 (p=0.012), respectively. There were 2 cases of hip dislocation in the THA group, and 2 cases in the BHA group underwent conversion to THA. Our short-term follow-up results were better for minimally invasive two-incision THA than for conventional BHA for the treatment of acute displaced femoral neck fractures in active elderly patients.

PURPOSE: To compare the clinical and radiologic outcomes of various surgical techniques for an isolated fracture of greater tuberosity of the humerus. MATERIALS AND METHODS: From February 2001 to December 2008, 31 patients, who underwent an operation for isolated greater tuberosity fracture and were followed up for more than 1 year, were enrolled in this study. The mean age at the time of operation was 49.3 years (range, 23-73 years). The operation methods included in this study were as follows: a transosseous suture using nonabsorbable suture material (16 cases), a fixation by cannulated screws (10 cases), tension band wiring (2 cases), bony fragment excision with rotator cuff repair (2 cases), and percutaneous pinning (1 case). RESULTS: At the last follow-up, the average Constant score was 79.4 and Korean Shoulder Score (KSS) was 81.2. Among the various operation methods used in this study, the transosseous suture had the highest scores with 82.5 in Constant score and 89.3 in KSS. Bone union was achieved at average 10.3 weeks (range, 7-15 weeks), and there were 2 cases in which the reoperation was required due to internal fixation failure. Postoperative shoulder stiffness occurred in 3 cases, and all the cases were done with the deltopectoral approach. CONCLUSION: Clinically and radiologically satisfactory results were obtained using various operation techniques for an isolated greater tuberosity fracture of the humerus. The transosseous suture showed relatively better results than the other methods used in this study. To achieve favorable clinical and radiologic results, it is important to select an appropriate surgical approach and fixation method according to the fracture site, degree of displacement, and size of fragment.

OBJECTIVE: To evaluate the factors that affect torque control during anterior retraction when utilizing the C-retractor with a palatal miniplate as an exclusive source of anchorage without posterior appliances. METHODS: The C-retractor was modeled using a 3-dimensional beam element (0.9-mm-diameter stainless-steel wire) attached to mesh bonding pads. Various vertical heights and 2 attachment positions for the lingual anterior retraction hooks (LARHs) were evaluated. A force of 200 g was applied from each side hook of the miniplate to the splinted segment of 6 or 8 anterior teeth. RESULTS: During anterior retraction, an increase in the LARH vertical height increased the amount of lingual root torque and intrusion of the incisors. In particular, with increasing vertical height, the tooth displacement pattern changed from controlled tipping to bodily displacement and then to lingual root displacement. The effects were enhanced when the LARH was located between the central and lateral incisors, as compared to when the LARH was located between the lateral incisors and canines. CONCLUSIONS: Three-dimensional lingual anterior retraction of the 6 or 8 anterior teeth can be accomplished using the palatal miniplate as the only anchorage source. Using LARHs at different heights or positions affects the quality of torque and intrusion.

Radicular cyst is the most common type of odontogenic cyst. The cyst originates from the maxilla occasionally, causes facial deformation and displacement of adjacent structures. An 11-year-old girl visited the outpatient clinic with the left cheek swelling and facial asymmetry. The cheek lesion was hard, accompanied by tenderness. The computed tomography (CT) scans revealed a large unilocular radicular cyst, which involved the floor of the left maxillary sinus, the palatine and alveolar process of the left maxilla. It was treated by transnasal marsupialization under endoscopic guidance. At the one postoperative year follow-up, facial asymmetry was restored and the marsupialization site was closed. The follow-up CT scan showed that the site of a radicular cyst was restored by bone formation. Therefore, we report a case of radicular cyst accompanied with facial asymmetry, which was restored after marsupialization. We also discuss the mechanism about the restoration of facial asymmetry.

Unexpected displacement of a dental implant into the maxillary sinus is an unusual but potential complication in dental procedure. A dental implant that migrates into the maxillary sinus often develops paranasal sinusitis and cause diverse peri-implant soft tissue complications. A 59-year-old man complaining of nasal obstruction for several months presented with a huge polypoid mass in the nasal cavity. He had undergone a dental implant procedure in the maxilla at a dental clinic seven years ago. The implant fixture was found displaced to the maxillary sinus. The migrated fixture and nasal mass were removed by endonasal endoscopic surgery and mini Caldwell-Luc operation. The pathology was diagnosed as an inverted papilloma. To our knowledge, this is the first case reported in the literature regarding a dental implant complication that developed independently of sinonasal inverted papilloma.

OBJECTIVE: The purpose of this study was to evaluate displacement of the mandibular condyle after orthognathic surgery using a condylar-repositioning device. METHODS: The patient group comprised 20 adults who underwent bimaxillary surgery between August 2008 and July 2011. The degree of condylar displacement was measured by pre- and postoperative tomographic analysis using centric relation bite and a wire during surgery. A survey assessing temporomandibular joint (TMJ) sound, pain, and locking was performed. The 20 tomographs and surveys were analyzed using the Wilcoxon signed-rank test and McNemar's test, respectively. RESULTS: No significant changes were observed in the anterior, superior, or posterior joint space of the TMJ (p > 0.05). In addition, no significant change was observed in TMJ sound (p > 0.05). However, TMJ pain and locking both decreased significantly after surgery (p < 0.05). CONCLUSIONS: Due to its simplicity, this method may be feasible and useful for repositioning condyles.

An abdominal advancement flap (AAF) is a flap that pulls the elevated abdominal skin up and creates the shape of the inferior portion of the breast by making a neo-inframammary fold. Seven patients underwent remodeling using an AAF or a method combining an AAF with other volume displacement techniques after partial mastectomy. The excision volume ranged from 15% to 35%. AAF with only mobilization of the gland flaps was performed in two cases, with lateral mammoplasty in one case, with the round block technique (RBT) in one case, with a modified RBT in one case, and with medial mammoplasty in two cases. Although one patient treated with a RBT had a partial blood-flow insufficiency of the nipple-areola complex, it improved with conservative treatment. The cosmetic results were found to be excellent in three cases, good in three, and fair in one case.

The Natrelle(TM) 410 (Allergan Inc., Irvine, CA, USA) shaped, form-stable silicone gel implant was introduced in Europe in 1993. Its "form stability" relates to increased cohesiveness or stiffness of the gel filler, allowing the implant to maintain its shape in the upright position. The anatomical form-stable implant is helpful for reducing ripples and provides more natural looking due to less upper pole fullness, so it has some benefits for the thin patients. And it provides more expansion to the lower pole, it has also benefits for the ptotic breasts or constricted breasts. I have experienced 69 cases with anatomical form-stable implants (52 Polytech Replicon(R) (POLYTECH Health & Aesthetics, Dieburg, Germany) implants, 85 Natrelle(TM) 410 implants) from February to December of 2012. The most common used implants are MF295 g of Natrelle(TM) 410 and high profile 315 g of Polytech Replicon(R). I did reoperations for 2 breasts of 2 patients. One was due to hematoma and the other was due to displacement. Both cases are my early experiences of shaped implants. There is no other complication yet. I need longer follow-up period for the appropriate evaluation. In my early experiences, the results of anatomical form-stable implants seem to make less fullness of upper pole, less ripples, more tightness, and similar recovery periods in contrast with the results of round textured implants.

PURPOSE: To present radiographic characteristics and report the clinical results of the operative treatment of Muller-Weiss disease. MATERIALS AND METHODS: This is a retrospective study including 13 patients, 14 feet who had been operated for Muller-Weiss disease between April 2006 and December 2011. Osteoarthritis of the peri-navicular joints were radiographically evaluated. Various range of peri-navicular fusion and joint-preserving surgeries according to patients' symptoms and radiographic findings were done. The clinical results were evaluated by American Orthopaedics Foot and Ankle Society (AOFAS) midfoot scale and visual analogue scale (VAS). RESULTS: On radiographs, osteoarthritic changes were presented at talonavicular joint in 11 cases, calcaneocuboid joint in 7 cases, subtalar joint in 6 cases, naviculo-cuneiform joint in 1 case. The mean anteroposterior talocalcaneal angle was 16.6 degrees. On hindfoot alignment view, 6 cases were varus, 5 cases were neutral and 3 cases were valgus alignment. Fusion comprised 6 cases in triple fusion, 1 case in talonavicular-cuneiform fusion, 2 cases in talonavicualr fusion and 1 case in talonavicular & calcaneocuboid fusion. Joint-preserving surgeries were bony fragment excision of the lateral part of navicular & medial displacement calcaneal osteotomy in 1 case, bony spur excision of talonavicular joint in 1 case and medial displacement calcaneal osteotomy in 2 cases. The postoperative AOFAS and VAS score were improved significantly (p=0.000, p=0.000). CONCLUSION: In cases of Muller-Weiss disease without osteoarthritic changes at peri-navicular joints, fragment excision of navicular, bony spur excision with or without medial displacement calcaneal osteotomy were effective operative treatments.

PURPOSE: Posteroanterior screw fixation is biomechanically stronger than anteroposterior screw fixation. However, there are few literature about the correlation between clinical results and more strength by posteroanterior fixation. This study was performed to evaluate the clinical outcomes of the accelerated rehabilitation following anterior open reduction and posterior percutaneous screw fixation for displaced talar neck fractures. MATERIALS AND METHODS: Eighteen cases were followed up for more than 1 year after posteroanterior fixation using headless compression screw for talar neck fractures. The clinical evaluation was performed according to American Orthopaedic Foot and Ankle Society (AOFAS) score and Hawkins criteria. As radiographic evaluation, the degree of fracture displacement, period to union, and occurrence rate of complications such as avascular necrosis through MRI were measured. RESULTS: The AOFAS score was average 90.4 points at the last follow-up. There were 7 excellent, 9 good, and 2 fair results according to the Hawkins criteria. Therefore, 16 cases(88.8%) achieved satisfactory results. The degree of fracture displacement had improved significantly from preoperative average 5.6 mm to 1.2 mm immediate postoperatively, and maintained to 1.1mm at the last follow-up. All cases achieved bone union, and the period to union was average 12.4 weeks. There were 3 cases of avascular necrosis of talar body and 2 cases of post-traumatic arthritis. CONCLUSION: Anterior open reduction and posterior percutaneous headless screw fixation seems to be an effective surgical method for displaced talar neck fractures, because of the possibility of accurate restoration of articular surface, fixation strength enough to early rehabilitation, and needlessness of hardware removal.

BACKGROUND: Increased intra-abdominal pressure during laparoscopic surgery causes cephalad displacement of the diaphragm, resulting in the formation of atelectasis, which can be overcome by positive end-expiratory pressure (PEEP). The aim of this prospective study was to investigate the level of optimal PEEP to maintain adequate arterial oxygenation and hemodynamics during robot-assisted laparoscopic radical prostatectomy (RLRP). METHODS: One hundred patients undergoing RLRP were randomly allocated to one of five groups (n = 20) (0, 3, 5, 7 and 10 cmH2O of PEEP). Hemodynamic variables and respiratory parameters were measured at baseline with the patient in the supine position; at 30 min, 1, 2, 3 and 4 h during CO2 insufflation with the patient in the post-Trendelenburg position; and after deflation in the supine position with increasing PEEP. RESULTS: The PaO2 levels and alveolar-arterial difference in oxygen tension (AaDO2) were improved in patients with PEEPs compared with patients in whom PEEP was not used. The application of PEEP (10 cmH2O) resulted in higher PaO2 levels compared to those with lower PEEP levels, but excessive peak airway pressure (PAP) was sometimes observed. The application of a PEEP of 7 cmH2O resulted in similar PaO2 levels without causing excessive PAP. There was a significant difference in central venous pressure between the groups, but there were no significant differences in heart rate, mean arterial pressure or minute ventilation between the groups. CONCLUSIONS: A PEEP of 7 cmH2O is associated with the greater improvement of PaO2 and AaDO2 without causing excessive PAP during RLRP.

Schwannomas are well-differentiated solitary benign tumors that originate from the schwann cells of the nerve sheath. They can readily occur in the head and neck regions, but the schwannoma originating from the infraorbital nerve is extremely rare and usually painless, slow-growing, and without specific symptoms. The author experienced a rare case of infraorbital schwannoma, which was completely removed through the intraoral approach. A 20-year-old woman was admitted to our hospital for a painless, solid and circular mass located on the right infraorbital region. The eyeball movement and visual field were normal. There was no globe displacement or proptosis. Preoperative computed tomography demonstrated 13x10x5 mm-sized soft tissue mass. On March 2011, the mass was removed through an intraoral approach. On histopathological examination, the gross specimen consisted of a smooth, well-encapsulated and light yellowish solid mass, measuring 12x7x5 mm. Microscopically, it presented a typical manifestation of schwannoma with Antoni A area with Verocay body, and Antoni B area on H&E stain. The result of the immunohistochemical staining was positive for the S-100 protein. The patient had hypoesthesia of the nasal septum and vestibule in the postoperative period, and this finding confirmed that the internal nasal branch of infraorbital nerve was the nerve in which the schwannoma originated. Infraorbital schwannomas are very rare and must be included in the differential diagnosis of the orbital masses inferior to the eyeball. In the case of early diagnosis, the small-sized infraorbital schwannomas can be completely removed without any scar through an intraoral approach.

Schmorl nodes represent displacement of intervertebral disc tissue into the vertebral body and have been considered as an asymptomatic incidental radiological finding on plain radiographs, computed tomography and magnetic resonance imaging (MRI). Although uncommon, acute symptomatic Schmorl nodes causing severe back pain do occur. We report here an unusual case of acute painful Schmorl node in a young healthy woman, with no previous trauma, presenting with a sudden significant localized back pain within hours accompanied by characteristic findings on a MRI scan. We reviewed all reports of symptomatic Schmorl nodes known in the literature, focusing mainly on MRI findings, and recent treatment options.

PURPOSE: To evaluate the radiological and clinical outcomes of intrapelvic anterior plate fixations for Day Classification Type II crescent fracture-dislocations of sacroiliac joints. MATERIALS AND METHODS: Ten patients who had undertaken the surgical treatment for the sacroiliac joint from 2006 to 2012 were enrolled in this study. All cases fell into Type II by Day Classification for sacroiliac joint injuries. For surgical treatments, the plate fixation through the intra-pelvic anterior approach was first performed for all cases and anterior ring fixation was performed in 4 cases with more severely displaced anterior pelvic ring injuries. Then, radiological and clinical evaluation was implemented. RESULTS: The bone union was observed from all patients whom performed the surgical fixation. In the radiological results, 9 cases with the anatomic and nearly-anatomic reductions were observed. Out of the 10 cases which performed the rotational displacement analysis, there were 3 excellent cases, 6 good cases and 1 fair case. The 10 cases that performed the deformity index and vertical displacement analysis, less variations were observed in the anterior ring fixations after intra-pelvic anterior plate fixation group. According to the clinical results, 4 excellent cases, 3 good cases, and 3 moderate cases were observed. CONCLUSION: In the Type II crescent fracture-dislocation of sacroiliac joint, the intrapelvic anterior plate fixation achieved satisfactory anatomical reductions, radiological stabilities and clinical results.

PURPOSE: We evaluated the results of arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures without cortical window along with any additional bone grafts. MATERIALS AND METHODS: From March 2006 to March 2009, twelve patients with arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures over 5 mm in depression and displacement on the articular surface in computed tomography (CT) were enrolled in this study. We reduced or removed the depressed fracture fragment using freer without making a cortical window. Then, we accomplished internal fixation by a cannulated screw. All cases have not received bone graft. Both the postoperative clinical and radiological results were evaluated by the Rasmussen system. RESULTS: The fractures were healed completely in an average of 9 (range from 7 to 12) weeks. According to Rasmussen classification, we obtained satisfactory clinical results as excellent in 8 cases, good in 3 cases, and fair in 1 case; and radiological results were excellent in 7 cases and good in 5 cases. CONCLUSION: We consider that arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures without cortical window and any additional bone grafts is are a useful methods for attaining satisfactory results.

Distal radius fractures are one of the most common types of fractures in the elderly. It is well documented that increased risk of a distal radius fracture in older patients is associated with decreased bone mineral density. Also, low bone mineral density increased severity of fracture and instability of fracture after reduction. Fracture displacement in the elderly does not necessarily result in functional impairment. Therefore, conservative treatment has been a mainstay treatment even in unstable fracture in the elderly. However, there is an increasing trend toward operative treatment recently, because functional demand increased in the elderly due to active life style and volar locking plate fixation enables the elderly early return to daily activity even in osteoporotic distal radius fracture.
